Questão jurídica principal
Whether the municipal councillor/teacher incompatibility under Aargau law was compatible with political rights and constitutional guarantees.
Decisão extraída
The incompatibility was based on sufficient statutory authority, pursued legitimate public interests, and was proportionate.
Fundamentação extraída
The canton may define incompatibilities to prevent concentration of public functions and preserve trust. Although no direct supervisory relation existed between the council and teachers, the legislature could still adopt a restrictive rule to avoid role concentration; the scheme stayed within cantonal discretion.
